Table 56. RAID Configuration Features (continued)
Feature RACADM Command Description
Force Offline
racadm storage
forceoffline:<PD FQDD>
This feature removes a drive from a
virtual disk configuration so that it
goes offline, resulting in a degraded VD
configuration. It is helpful if a drive is
likely to fail in near future or is reporting
a SMART failure but is still online. It can
be also used if you would like to utilize
a drive which is part of an existing RAID
configuration.
Replace Physical Disk
racadm storage
replacephysicaldisk:<Source
PD FQDD > -dstpd
<Destination PD FQDD>
Allows you to copy data from a physical
disk which is a member of a VD, to
another physical disk. The source disk
should be in online state, while the
destination disk should be in ready state
and of a similar size and type to replace
the source.
Virtual Disk as boot device
racadm storage
setbootvd:<controller
FQDD> -vd <VirtualDisk
FQDD>
A virtual disk can be configured as
a boot device using this feature. This
enables fault tolerance when a VD with
redundancy is selected as the boot
device, and also has the operating
system installed on it.
Unlock Foreign Configuration
racadm storage
unlock:<Controller FQDD>
-key <Key id> -passwd
<passphrase>
This feature is used to authenticate
locked drives which have a different
source controller encryption than the
destination. Once unlocked, the drive
can be successfully migrated from one
controller to another.
